| A new alpheid shrimp, Thuylamea camelus gen. nov. & spec. nov., from Dong Hoa, a coastal community of Can Gio district, and northwest of Vung Tau (Cap St. Jacques), Vietnam, is described and illustrated. The new genus appears not to be closely related to any of the previously described genera. It has the postero-dorsal margin of the carapace armed with two high and short crests which are slightly outward inclined and directed backward, and between these crests with a low but distinct conical spine, and an elevated conical boss in the anterior median area slightly behind the anterior margin of the first abdominal somite. |

| A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato, resulting in one new family, Hypothalassiidae. Four xanthoid families are elevated to superfamily status, resulting in Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, and Goneplacoidea, and numerous subfamilies are elevated to family status. The Mathildellidae is moved from the Goneplacidae to the Portunoidea. Diagnoses for all superfamilies and families discussed herein are provided, embracing characters typically used by biologists as well as readily fossilized features of the dorsal carapace, sternum, abdomen, and chelipeds. All genera known from the fossil record at one time referred to the Xanthidae... |

| A new species of porcellanid crab, Polyonyx vermicola, belonging to the P. sinensis group is described from Selangor, Peninsular Malaysia. The species is an obligate commensal of tubes of the chaetopterid worm Sasekumaria selangora Rullier, 1976 (Polychaeta). Polyonyx vermicola is differentiated from all congeners by its small size, possessing a more rectangular carapace, proportionately longer carpus on the larger cheliped, strongly gaping cheliped fingers, the tips of which are turned outwards, the outer surface of each cheliped fingers lined with a row of small granules, and having the ventral margin of the third ambulatory propodus armed with strong spinules. |

| Understanding of antimicrobial defence mechanisms of penaeid shrimp should help in the design of efficient strategies for the management and disease control in aquaculture. In this study, we have specifically analysed the expression in circulating hemocytes of antimicrobial peptides (AMPs) encoding genes, such as PEN2 and PEN3, ALF, crustin, lysozyme and a putative cysteine-rich peptide. We evidenced a relationship between the level of expression of some AMPs and the successful response of the shrimp, Litopenaeus stylirostris, to circumvent a pathogenic Vibrio penaeicida infection. Additionally, significant differences in some AMP transcript amounts are evidenced between control, non-selected shrimp line and the third generation breeding of shrimp selected... |

| A study of major collections led to a revision of the Indo-Pacific leucosioid genus Myra Leach, 1817. The systematic status and nomenclatural disposition of each species was assessed, and many were diagnosed based on examination of the type material. A new genus, Myrine, is established for M. acutidens (Ihle, 1918) and M. kesslerii (Paulson, 1875). The genus Myrodes Bell, 1855, is synonymized with Myra. Nine species are retained as valid: M. affinis Bell, 1855, M. australis Haswell, 1880, M. brevimana Alcock, 1896, M. elegans Bell, 1855, M. eudactyla (Bell, 1855), M. fugax (Fabricius, 1798), M. grandis Zarenkov, 1990, M. mammillaris Bell, 1855, and M. subgranulata Kossmann, 1877. Five new species are established: M. celeris, M. currax, M. curtimana, M.... |

| The digestive tract of crustacea is complex. It is composed of a shor t oesophagum, a stomach with two bags, and internal wall with appendags specialized in grinding of feeds. These hard mastication pieces represent the gastric mill. Setae, filters included in the stomach structure allow the separation between food particles and liquid compounds. Those one are coming over through filters and more on to the digestive gland tubules or mid gut gland. In this organ, several types of cells play specialized functions: absorption, enzyme secretion, stocking function. Some cells of a new type, with undefined function, may be neurosecretions function, have been described recently. The end of tubules of digestive gland exhibits cells with embryonic characteristics.... |

| The reproductive aspects of the freshwater shrimp Potimirim glabra (Kingsley, 1878) were studied from September 1997 to February 1999. Monthly, samples were collected with sieves, on the river edge, under the edging vegetation or in small pools. At the laboratory, shrimps were sexed and measured in their total lenght, from the tip of the rostrum to the end of telson with precision callipers. The ovigerous shrimps were separated and counted for fecundity determination. The eggs diameter was measured with calibrated stereomicroscope. A total of 3281 shrimps were collected, among which, 47% male, 46% female (13.4% ovigerous females) and 7% young shrimps. The Sex ratio was 1:1. Ovigerous females were present during all seasons, but the reproductive peak... |

| This study is an attempt to produce an assessment of the impact of shrimp aquaculture in the Mekong Delta (Viet Nam) on mangrove ecosystems. For this exercise we selected two sub-areas (Ca Mau and Tra Vinh provinces) encompassing a variety of land uses and ecological conditions. Twenty stations in Tra Vinh and 15 stations in Ca Mau have been surveyed several times from September 2000 to March 2002. Field investigations included mangrove soils studies, measurements of pH and salinity of the water, analysis of mangrove flora, and density and structure of the vegetation. Four Systeme Probatoire de l'Observation de la Terre (SPOT) scenes were used for the discrimination of mangrove types and for the delineation of landscape units. For the first time, five... |
